Chemical Identity & Classification

YK-11 is precisely identified by CAS number 1370003-76-1, ensuring its standardized recognition across global chemical databases and regulatory references. The molecular formula C25H34O6 yields a molecular weight of 430.53 g/mol, providing researchers with accurate metrics for stoichiometric calculations and experimental design. Synonyms include Myostine, YK-11-OA, and (17α,20E)-17,20-[(1-methoxyethylidene)bis(oxy)]-3-oxo-19-norpregna-4,20-diene-7α-yl acetate, classifying it as a steroidal synthetic compound designated as an analytical reagent and reference standard for laboratory use. This positions it within the category of selective research materials for in vitro structural and binding analyses by trained scientific personnel.

Chemical & Physical Characteristics

YK-11 Powder manifests as a white to off-white crystalline solid, offering optimal flowability and precision in laboratory weighing and transfer operations. It exhibits solubility in DMSO (up to 64 mg/mL with sonication), moderate solubility in methanol and chloroform, and low water solubility, informing solvent selection for dissolution and extraction protocols. Key physical metrics include a predicted density of 1.22 g/cm³, storage stability at -20°C, and sensitivity to light and moisture, which necessitate protected handling. The compound’s solid form supports reproducible outcomes in techniques such as High-Performance Liquid Chromatography (HPLC), mass spectrometry, and nuclear magnetic resonance (NMR) spectroscopy, delivering neutral data for analytical validation without implying functionality.

Purity & Analytical Verification

Each batch of YK-11 Powder is verified to ≥98% purity through a suite of orthogonal analytical techniques, including HPLC (for primary purity assessment), LC-MS (for molecular confirmation), NMR (for structural elucidation), and GC (for volatile impurities). These methods quantify contaminants below detectable limits, such as heavy metals under 5 ppm and residual solvents compliant with ICH guidelines, ensuring suitability for high-precision reference applications. A comprehensive Certificate of Analysis (COA) accompanies every lot, outlining purity percentages, impurity profiles, spectral data, and method specifics, readily available for researcher review and archival. This rigorous verification protocol guarantees material reliability across extended experimental campaigns.

Quality Control & Batch Integrity

Manufacturing of YK-11 Powder adheres to batch-specific protocols, with each production run assigned a unique lot number enabling complete traceability from initial synthesis through final packaging and distribution. Quality assurance incorporates in-process controls for yield consistency, intermediate purity checks, and final third-party validations to confirm physical uniformity and chemical integrity. Retention samples are archived under validated conditions, paired with detailed stability studies demonstrating shelf-life viability exceeding 24 months when properly stored. Comprehensive documentation, including raw material sourcing logs and environmental monitoring records, provides laboratories with the assurance needed for multi-batch comparative research and regulatory audits. This end-to-end integrity framework eliminates variability, supporting dependable results in serial dosing simulations or long-term stability trials.

Safety, Handling & Laboratory Precautions

Laboratory handling of YK-11 Powder demands adherence to institutional safety standards, utilizing full Personal Protective Equipment (PPE) ensembles comprising nitrile gloves, safety goggles, laboratory coats, and respiratory protection within certified fume hoods. Transfer operations should employ enclosed spatulas or automated dispensers to minimize aerosol generation, with any spills contained using inert absorbents and neutralized per SDS guidelines. The Safety Data Sheet (SDS) classifies potential hazards under GHS categories for irritancy (skin, eye, respiratory), mandating immediate rinsing for exposures and prohibiting open-air manipulations. Waste streams must follow hazardous chemical disposal regulations, including segregation and incineration, under supervision of certified personnel only. These precautions maintain a secure research environment devoid of non-laboratory implications.

Packaging, Labeling & Storage

YK-11 Powder is packaged in research-grade, light-impermeable amber glass vials or high-density polyethylene (HDPE) bottles featuring tamper-evident seals and oxygen absorbers to safeguard against oxidative degradation. Labels conform to GHS and international standards, prominently displaying CAS 1370003-76-1, molecular formula C25H34O6, ≥98% purity declaration, batch identifier, hazard symbols, and storage directives. Recommended storage at -20°C in a desiccator or inert-atmosphere freezer preserves chemical stability for up to 36 months, with aliquoting advised to prevent repeated thermal cycling. Upon receipt, equilibrate to ambient conditions prior to opening to avoid condensation-induced clumping.

Intended Research Use & Market Positioning

YK-11 Powder is tailored for analytical chemistry laboratories, pharmaceutical R&D for reference calibration, forensic science validations, and academic institutions conducting synthetic steroid analog studies. It facilitates investigations into receptor binding kinetics, follistatin expression profiling, myogenic differentiation models, and osteogenic activity in cellular assays—all within in vitro confines. As a generic, high-purity (≥98%) equivalent to proprietary materials, it offers cost efficiencies for high-volume screening without compromising analytical rigor. This positions YK-11 Powder as a versatile staple in workflows spanning structure-activity relationship (SAR) mapping, impurity fate tracking, and cross-analyte comparisons in legitimate scientific pursuits.
