1,8-bis(methoxymethoxy)naphthalene CAS 172915-62-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,8-bis(methoxymethoxy)naphthalene.

1,8-bis(methoxymethoxy)naphthalene (CAS 172915-62-7), molecular formula C14H26O4 and molecular weight 258.35 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 1,8-bis(methoxymethoxy)naphthalene is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 258.35 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.

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.

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.
