Chemical Structure

BSTFA-TMCS CAS 152571-61-4 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 BSTFA-TMCS.

BSTFA-TMCS (CAS 152571-61-4) is a high-purity analytical reference standard with the molecular formula C8H18F3NOSi2C3H9ClSi and a molecular weight of 366.04 g/mol.

Structurally, BSTFA-TMCS (C8H18F3NOSi2C3H9ClSi) contains an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of -3.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 366.04 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
