Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Ethoxycarbonyl-5-methyl-(3R)-3-tert-butyl-dimethylsilyloxypentanedioate.
1-Ethoxycarbonyl-5-methyl-(3R)-3-tert-butyl-dimethylsilyloxypentanedioate (CAS 158275-79-7), molecular formula C15H28O7Si and molecular weight 348.46 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 1-Ethoxycarbonyl-5-methyl-(3R)-3-tert-butyl-dimethylsilyloxypentanedioate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 348.46 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
