What is Cyclopentanecarbaldehyde CAS 872-53-7?

Cyclopentanecarbaldehyde CAS 872-53-7, also named cyclopentanecarboxaldehyde or cyclopentylmethanal, is a five-membered cyclic aldehyde with the molecular formula C6H10O and a molecular weight of 98.14 g/mol. It is normally supplied as a colorless to pale yellow liquid.

What is Cyclopentanecarbaldehyde used for in organic synthesis?

It is primarily used as a reactive aldehyde building block in pharmaceutical, agrochemical and dyestuff synthesis. The cyclopentane ring and aldehyde group allow it to be converted into more complex intermediates through condensation, reduction, oxidation and other common synthetic steps.

What are the typical purity and physical data for Cyclopentanecarbaldehyde?

The catalog product is usually offered at 98.0% purity or higher, with appearance as a colorless to pale yellow liquid. Typical physical values include a boiling point near 140-141 C, density around 0.919 g/mL at 25 C, and a refractive index reported in the approximate 1.439-1.535 range depending on the source and measurement conditions.

Why is Cyclopentanecarbaldehyde considered a flammable liquid?

Its closed-cup flash point is approximately 28-30 C, so vapors can ignite near common ambient temperatures. It should be stored in a cool, well-ventilated area in tightly closed containers and kept away from open flames, sparks, hot surfaces and other ignition sources.

What should buyers confirm before using Cyclopentanecarbaldehyde CAS 872-53-7?

Buyers should confirm the exact CAS number, molecular formula, purity, appearance and batch consistency with the intended reaction scale. Storage temperature and packaging are also important because the low flash point and liquid state affect safe handling and transport.
