Product Overview

CBD Powder CAS 13956-29-1 represents a brandless, high-purity (≥98%) research chemical supplied strictly for laboratory and analytical research. This fine powder morphology supports uniform particle distribution essential for accurate chromatographic method development and spectrometric characterization within professional research facilities. For research use only. Not for human or veterinary use. Not for clinical, diagnostic, or consumptive applications. Analytical chemists utilize its consistent physical properties for reproducible quantitative analyses across HPLC, GC-MS, LC-MS/MS, and NMR platforms.

The powder’s optimized micronization (D90 <100 μm) ensures minimal static adhesion during transfers while maximizing dissolution kinetics in standard laboratory solvents. Researchers acquire it through compliant eCommerce platforms to maintain supply continuity for systematic phytocannabinoid analog profiling and reference standard validations. Bulk flow characteristics enable efficient volumetric dispensing critical for constructing multi-point calibration curves spanning 0.1-100 μg/mL ranges.

Institutional laboratories integrate CBD Powder into validated workflows requiring characterized cannabinoid references for QC matrices, proficiency testing panels, and inter-laboratory comparisons. Comprehensive batch documentation facilitates LIMS incorporation while satisfying ISO 17025 accreditation standards. Reliable commercial availability prevents disruptions to longitudinal stability programs and accelerated degradation studies.

This research chemical contributes objective structural data to comparative analyses of terpenophenolic cannabinoids, supporting method optimization conducted exclusively under controlled laboratory conditions.

Chemical Identity & Classification

CBD Powder CAS 13956-29-1 features CAS number 13956-29-1, molecular formula C21H30O2, and molecular weight 314.46 g/mol. Synonyms include Cannabidiol, (-)-Cannabidiol, and 2-[(1R,6R)-6-isopropenyl-3-methylcyclohex-2-enyl]-5-pentylbenzene-1,3-diol, classifying it as a phytocannabinoid analytical reference standard. Formal designation limits application to laboratory reagent use.

IUPAC nomenclature (6aR,10aR)-6a,7,8,10a-tetrahydro-6,6,9-trimethyl-3-pentyl-6H-dibenzo[b,d]pyran-1-ol defines stereospecific configuration essential for chiral method development. This identification enables discrimination from Δ9-THC, Δ8-THC, and exo-THC isomers during LC-HRMS workflows. Classification aligns with non-psychoactive cannabinoid reference materials for forensic and natural products research.

Molecular descriptors include cLogP 6.31, TPSA 40.46 Ų, three hydrogen bond donors, facilitating retention modeling across C18, biphenyl, and HILIC stationary phases. Standardized synonyms streamline database retrieval while maintaining research-only parameters.

Chemical & Physical Characteristics

CBD Powder appears as white to off-white crystalline powder characteristic of high-purity phytocannabinoids. Solubility profiles confirm ethanol (50 mg/mL), DMSO (125 mg/mL), DMF (100 mg/mL), and acetonitrile (25 mg/mL) compatibility, supporting diverse mobile phase compositions. Melting point registers 66-67°C ideal for thermal profiling via DSC.

Powder flow classifies as free-flowing (Carr Index 12-16%) enabling precise microgram weighings on analytical balances. UV absorbance maxima (225, 276 nm) optimize DAD detection limits to 0.05 μg/mL. Dual pKa values (carboxylic 7.0, phenolic 9.5) enable comprehensive speciation across pH 2-12 gradients.

Post-dissolution particle distribution maintains uniformity preventing injection valve clogging. Residual moisture content <0.5% KF preserves oxidative stability under ambient conditions (40-60% RH).

Purity & Analytical Verification

Purity exceeds 98%, orthogonally confirmed via RP-HPLC (>99.0% peak area), GC-FID, quantitative 13C-NMR, and ESI-LC-MS. Certificates of Analysis specify Δ9-THC <0.05%, CBN <0.10%, CBC <0.15%, individual unknowns <0.10%, total impurities <1.0%. Residual solvents meet USP <467> limits (Class 1-3).

HPLC utilizes Acquity BEH C18 (50×2.1 mm, 1.7 μm) with 0.1% formic acid/IPA gradient, resolving CBD from CBG/CBN/Δ9-THC (Rs >2.5). 600 MHz 1H-NMR (CDCl3) verifies diagnostic signals: 5.40 ppm (dd, vinyl H-2′), 1.68 ppm (s, gem-dimethyl), 0.87 ppm (t, pentyl CH3). HRMS confirms [M+Na]+ m/z 337.2136 (calc. 337.2138, Δ<0.6 ppm).

COAs include raw chromatograms overlaid with USP/NIST reference spectra. ICH Q2 validation demonstrates linearity r²≥0.9998 (0.5-500 μg/mL), accuracy 99.5-100.5%, precision RSD <0.5% at 80/100/120% levels.

Quality Control & Batch Integrity

Extraction employs ethanol/water precipitation from carrier-free hemp isolates followed by preparative SFC purification (>99.5% ee). Lot traceability spans biomass cultivation records through final milling via serialized blockchain integration. In-process XRPD confirms amorphous/crystalline ratio stability.

Release testing includes chiral LC (>99.9% R-enantiomer), microbial limits (TAMC <10 CFU/g), heavy metals (ICP-MS <1 ppm Pb/Cd/Hg/As), and residual pesticides (LC-MS/MS 400+ compounds). Third-party ISO 17025 labs execute blind proficiency against NIST SRM 1575a.

SPC maintains process capability Cpm >1.50 across fourteen critical quality attributes. Accelerated stability (ICH Q1A 40°C/75%RH/6mo) predicts 48-month shelf life.

Safety, Handling & Laboratory Precautions

Handle exclusively under Type B2 total-exhaust fume hoods (>110 fpm) wearing nitrile gloves (15 mil), ANSI Z87.1 goggles, Tychem® C coveralls, and P100 respirators. Weighing operations conduct within containment isolators (<0.5 μg/m³). SDS classifies Eye Dam. 1 H318, Skin Irrit. 2 H315, STOT SE 3 H336.

Local exhaust systems capture volatiles to <0.1 ppm. Spill protocol utilizes Diatomaceous earth absorption, isopropyl alcohol rinse, and HEPA vacuum recovery. Waste streams classify non-DOT per 40 CFR 261.4(b).

Emergency deluge units position within 10s travel distance; annual EHS drills validate response competency.

Packaging, Labeling & Storage

Primary packaging utilizes USP Type I 5 mL glass vials with PTFE-lined septa and magnetic stir bars for dissolution studies. Secondary 95 kPa pouches enable air shipment. GHS labels specify UN3077, Packing Group III, Marine Pollutant.

Storage requires 2-8°C desiccated (<20% RH), light excluded from oxidizing agents/peroxides. Photostability data confirm <0.2% degradation (ICH Q1B 1.2E6 lux-hr). XRPD verifies polymorphic stability through 36 months.
