Does the name Beryllium Phosphide alone establish the formula Be3P2?

No. The elemental ratio must be stated explicitly. CAS 58127-61-0 is associated with Be3P2, containing beryllium and phosphorus in a 3:2 atomic ratio. Do not match material by the English name alone when another formula is shown. Confirm the formula, CAS number, elemental composition and agreed identity documentation.

What must be confirmed before sourcing Beryllium Phosphide Be3P2?

Define purity and its calculation basis, elemental or trace-metal analysis, particle form and size, oxygen and moisture controls, package construction and quantity. Because beryllium compounds and phosphide materials require specialized controls, the intended use, destination regulations, facility capability, transport classification, current SDS and acceptance of the proposed package must be reviewed before supply.

Beryllium Phosphide (Be3P2) CAS 58127-61-0

Beryllium Phosphide (Be₃P₂), CAS 58127-61-0, EC 261-137-1, is a beryllium–phosphorus compound with molecular weight 88.98 g/mol. The previously displayed CAS 12232-25-6 identifies beryllium selenide, not this phosphide, and has been removed. Beryllium compounds present serious chronic health hazards, while phosphide chemistry requires strict moisture and gas-evolution controls. This material is offered only for qualified research with a documented technical need, legal review, exposure-control plan and current SDS.

CAS: 58127-61-0
Synonyms: Beryllium Phosphide, Triberyllium diphosphide, Beryllium phosphide (Be3P2), Be3P2

Identity and physicochemical profile

Item	Technical guidance
Correct identity	Beryllium phosphide; triberyllium diphosphide; Be₃P₂
CAS / EC	58127-61-0 / 261-137-1
Formula / molecular weight	Be₃P₂ / 88.98 g/mol
Corrected conflict	CAS 12232-25-6 belongs to beryllium selenide, BeSe, and must not be used for Be₃P₂
Key purchase controls	Phase and identity data, elemental composition, purity basis, trace metals, particle form, moisture exposure and package integrity
Supply boundary	Controlled research material requiring prior safety, legal, facility and end-use review

Applications and grade selection

Beryllium Phosphide may be considered only for specialized solid-state, inorganic or materials research where its exact phase and composition are technically justified. Generic semiconductor, industrial-volume or open-handling claims are inappropriate without project data. Buyers must qualify the actual material by phase, elemental composition, impurity profile and performance.

Define the required Be₃P₂ phase, purity calculation, particle form, trace-metal limits and characterization methods.
Confirm that the receiving facility can control beryllium exposure, moisture contact, contaminated waste and emergency response.
Review legal status, end use, package, transport feasibility and documentation before requesting a sample.

Storage and handling

Maintain the sealed moisture-protective package under the conditions specified in the current SDS and supplier instructions. Segregate it from water, acids and incompatible materials, and use a controlled procedure for opening, sampling, resealing and contaminated-container management.

Safety, documentation and procurement

Beryllium compounds are highly hazardous and require stringent inhalation and contamination controls. Contact with moisture or acids may create additional phosphide-related gas hazards. Procurement is conditional on qualified personnel, suitable engineering controls, end-use disclosure and destination compliance.
