Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 77572-72-6 Silabolin Estr-4-en-3-one, 17-methyl-17-((trimethylsilyl)oxy)-, (17beta)- Estr-4-en-3-one, 17-beta-((trimethylsilyl)oxy)- Estr-4-en-3-one, 17-methyl-17-((trimethylsilyl)oxy)-, (17-beta)- 17-Methyl-17-beta-((trimethylsilyl)oxy)estr-4-en-3-one 19-Nortestosterone-17-trimethoxysilyl ether Silaboline.

CATO supplies 77572-72-6 Silabolin Estr-4-en-3-one, 17-methyl-17-((trimethylsilyl)oxy)-, (17beta)- Estr-4-en-3-one, 17-beta-((trimethylsilyl)oxy)- Estr-4-en-3-one, 17-methyl-17-((trimethylsilyl)oxy)-, (17-beta)- 17-Methyl-17-beta-((trimethylsilyl)oxy)estr-4-en-3-one 19-Nortestosterone-17-trimethoxysilyl ether Silaboline (CAS 77572-72-6), a certified reference material (molecular formula C22H36O2Si, MW 360.61 g/mol) for analytical method development and quality control.

77572-72-6 Silabolin Estr-4-en-3-one, 17-methyl-17-((trimethylsilyl)oxy)-, (17beta)- Estr-4-en-3-one, 17-beta-((trimethylsilyl)oxy)- Estr-4-en-3-one, 17-methyl-17-((trimethylsilyl)oxy)-, (17-beta)- 17-Methyl-17-beta-((trimethylsilyl)oxy)estr-4-en-3-one 19-Nortestosterone-17-trimethoxysilyl ether Silaboline (C22H36O2Si) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures 77572-72-6 Silabolin Estr-4-en-3-one, 17-methyl-17-((trimethylsilyl)oxy)-, (17beta)- Estr-4-en-3-one, 17-beta-((trimethylsilyl)oxy)- Estr-4-en-3-one, 17-methyl-17-((trimethylsilyl)oxy)-, (17-beta)- 17-Methyl-17-beta-((trimethylsilyl)oxy)estr-4-en-3-one 19-Nortestosterone-17-trimethoxysilyl ether Silaboline under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
