Stearic Acid Extra Pure – 500 gram Packs

Stearic acid is a saturated long-chain fatty acid supplied for scientific and laboratory work. It is identified by its white waxy flakes or crystalline solid and its characteristic chemical behaviour: is poorly soluble in water and melts near 69–70 °C. In educational and research settings, this material is relevant to melting-point and organic chemistry studies. Its experimental value depends on appropriate preparation, accurate identification, and observance of the relevant safety controls. Laboratory users should consider solubility, compatibility, concentration and stability when designing procedures, especially when standardising solutions or comparing results. The listed 500 gram Packs is a purchasing format, not evidence of a particular analytical performance standard. Use the current safety data and the actual label to confirm which methods are appropriate for the supplied reagent.

Frequently Asked Questions About Stearic acid

What is Stearic acid used for in laboratories?

Stearic acid is relevant to melting-point and organic chemistry studies. Examples include melting point determination exercises and acid-base titration in suitable solvent systems. The appropriate method depends on the composition, working concentration and laboratory safety controls. Some specialised investigations require additional validated conditions.

What chemical formula and molecular weight apply to Stearic acid?

The reference formula is C18H36O2, with molecular weight 284.48 g/mol. For polymers, formulated media, uncertain borates or salts available as hydrates, these entries must not be treated as guaranteed specifications of an unspecified commercial form.

What is the CAS number of Stearic acid?

The CAS entry is 57-11-4. This identification refers to the stated reference substance where applicable. If the product is a mixture or an unspecified hydrate, the exact supplied formulation should be verified before assigning a substance-specific identifier.

Can Stearic acid be used for teaching and research?

It can support appropriate supervised work involving melting-point and organic chemistry studies. Suitability is not universal: required grade, exact composition, method sensitivity, equipment and facility safety controls must be assessed. More hazardous or reactive substances should only be handled by appropriately trained personnel.

How should Stearic acid be stored and handled?

Store closed in a cool, dry area away from strong oxidisers and excessive heat. Avoid dust or heated vapour exposure, use suitable PPE, and take care when heating molten samples. Review the current SDS and the institution’s disposal and emergency procedures before performing experiments.

Storage Conditions for Stearic acid

Store closed in a cool, dry area away from strong oxidisers and excessive heat. Keep the product clearly labelled and review its current safety data for any grade- or formulation-specific conditions. Do not expose it to incompatible materials, and use suitable containment for the listed chemical form.

Precautions for Handling Stearic acid

Read the current Safety Data Sheet before use. Avoid dust or heated vapour exposure, use suitable PPE, and take care when heating molten samples. Avoid unnecessary inhalation, ingestion and skin or eye contact. Use suitable ventilation and follow institutional spill-response, emergency and waste-disposal protocols. Where experiments involve hazardous reactions, ensure appropriate supervision and compatible protective equipment.
