Frequently Asked Questions

What is diethyl malonate used for?

Diethyl malonate (CAS 105-53-3) is a versatile active-methylene reagent used as a chemical intermediate in fine-chemical manufacture, including agrochemical actives, flavor and fragrance precursors, and specialty malonate esters. Its acidic methylene group enables carbon-carbon bond formation in synthesis. RawSource supplies it in bulk to fine-chemical and agrochemical producers.

What is another name for diethyl malonate?

Diethyl malonate is also called diethyl propanedioate, malonic acid diethyl ester, and DEM (in the malonate context). Its CAS number is 105-53-3 and formula is C7H12O4.

What is the difference between diethyl malonate and dimethyl malonate?

Both are diesters of malonic acid and active-methylene reagents; diethyl malonate carries two ethyl groups (C7H12O4) while dimethyl malonate carries two methyl groups, giving a lower molecular weight and boiling point. The ester choice affects volatility and downstream product in the same condensation chemistry.

What is the CAS number for diethyl malonate?

Diethyl malonate's CAS number is 105-53-3, molecular formula C7H12O4, classified under HS 2917.19. RawSource provides a Certificate of Analysis and SDS with each bulk shipment.

What is the cost of bulk diethyl malonate?

Bulk diethyl malonate pricing depends on volume, packaging (drums or totes), and freight. RawSource quotes against current supply; request a bulk quote with your volume and ship-to for current pricing.
