About Bis(2-(2-butoxyethoxy)ethoxy)methane

Bis(2-(2-butoxyethoxy)ethoxy)methane is an API impurity reference standard carrying the CAS registry number 143-29-3. With the molecular formula C17H36O6, it has a molar mass of 336.5 g/mol. The IUPAC name is 1-[2-[2-[2-(2-butoxyethoxy)ethoxymethoxy]ethoxy]ethoxy]butane. Alternative names: 5,8,11,13,16,19-Hexaoxatricosane and Butylcarbitol formal.

It is supplied as a solid. Reference materials should be stored sealed and away from light and moisture, as specified on the accompanying COA. The GHS classification uses the signal word “Warning”, so appropriate gloves, eye protection and ventilation are recommended.

As a characterised impurity of the parent drug substance, it is used for analytical method development, method validation (AMV) and routine quality-control testing, and it supports ANDA and DMF regulatory filings. Our customers for this product work in pharmaceutical manufacturing and academic and industrial research.

Standard pack sizes are 10 mg, 25 mg, 50 mg and 100 mg, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
