3,4-Dichloro-4-pyrrolidinomethyl benzophenone CAS 898776-85-7 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 3,4-Dichloro-4-pyrrolidinomethyl benzophenone.

3,4-Dichloro-4-pyrrolidinomethyl benzophenone (CAS 898776-85-7), molecular formula C18H17Cl2NO and molecular weight 334.24 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3,4-Dichloro-4-pyrrolidinomethyl benzophenone (C18H17Cl2NO) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 334.24 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
