Chemical Structure

1-[3,4-Bis(phenylmethoxy)phenyl]-1-propanone 17269-65-7 3',4'-Bis(benzyloxy)propiophenone 3',4'-Dibenzyloxy-1-phenylpropiophenone CAS 17269-65-7 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-[3,4-Bis(phenylmethoxy)phenyl]-1-propanone 17269-65-7 3',4'-Bis(benzyloxy)propiophenone 3',4'-Dibenzyloxy-1-phenylpropiophenone.

1-[3,4-Bis(phenylmethoxy)phenyl]-1-propanone 17269-65-7 3',4'-Bis(benzyloxy)propiophenone 3',4'-Dibenzyloxy-1-phenylpropiophenone (CAS 17269-65-7), molecular formula C23H22O3 and molecular weight 346.42 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, a hydroxyl group, an ether linkage, 1-[3,4-Bis(phenylmethoxy)phenyl]-1-propanone 17269-65-7 3',4'-Bis(benzyloxy)propiophenone 3',4'-Dibenzyloxy-1-phenylpropiophenone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 346.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
